Best ROI on Bought Followers

I'm looking to buy the most amount of Instagram followers possible. Can be low quality, looking for volume - just trying to get the number up there. Even if it kills the engagement its just a test account anyway.
Recommendations for cheapest with highest volume?

can rather throw the money in the trash bin, nevertheless a simple search around the marketplace could get you in touch with different sellers. Bet if you're willing to go big they can quote you special fees.
